The low induction efficiency may reflect the need for precise timing, balance, & absolute levels of expression of the reprogramming genes. It may also suggest a need for rare genetic and/or epigenetic changes in the original somatic cell population or in the prolonged culture. Depletion of Mbd3 improves reprogramming efficiency.

Reprogramming of adult cells to obtain iPSCs never increase the risk of tumorigenecity.
A. 对
B. 错
Incomplete reprogramming is particularly challenging during iPSC generation because the genome-wide epigenetic code must be reformatted to that of the target cell type in order to fully reprogram a cell.

Three separate groups were able to find mouse embryonic fibroblast (MEF)-derived iPSCs that could be injected into tetraploid blastocysts & resulted in the live birth of mice derived entirely from iPSCs, thus enhancing the debate over the equivalence of ESCs & iPSCs with regard to pluripotency.
